Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Develop a complete CFG for a simple programming language that allows basic arithmetic expressions. Derive the string (2 + 3) * (4 - 1) and create its parse tree.

💡 Hint: Focus on breaking the expression down into terms and operations.

Challenge 2 Hard

Analyze why parse trees are important for syntax checking in compiler design. Provide examples of scenarios where derivation errors could affect program execution.

💡 Hint: Think about how structure relates to error detection in code.
